* feat: disable directory listings for static files
Static file server handles serving static asset files (js, css, etc).
The default file server would also list all files in a directory.
This has been changed to only serve files.
* chore: add database test fixture to insert non-unique linked_ids
* chore: create unit test to exercise failed email change bug
* fix: add postgres triggers to keep user_links clear of deleted users
* Add migrations to prevent deleted users with links
* Force soft delete of users, do not allow un-delete
* fix: assign new oauth users to default org
This is not a final solution, as we eventually want to be able
to map to different orgs. This makes it so multi-org does not break oauth/oidc.
* fix: assign new oauth users to default org
This is not a final solution, as we eventually want to be able
to map to different orgs. This makes it so multi-org does not break oauth/oidc.
The first organization created is now marked as "default". This is
to allow "single org" behavior as we move to a multi org codebase.
It is intentional that the user cannot change the default org at this
stage. Only 1 default org can exist, and it is always the first org.
Closes: https://github.com/coder/coder/issues/11961
I noticed a possible race where tailnet.Conn can try to dial the embedded region before we've set our custom dialer that send the DERP in-memory. This closes that race and adds a test case for servertailnet with no STUN and an embedded relay
I think this will resolve#12136 but lets get a proper test at the system level before closing.
Before this change, we only register the node callback at start of day for the server tailnet. If the coordinator changes, like we know happens when we are licensed for the PGCoordinator, we close the connection to the old coord, and open a new one to the new coord.
The callback is designed to direct the updates to the new coordinator, but there is nothing that specifically triggers it to fire after we connect to the new coordinator.
If we have STUN, then period re-STUNs will generally get it to fire eventually, but without STUN it we could go indefinitely without a callback.
This PR changes the servertailnet to re-register the callback each time we reconnect to the coordinator. Registering a callback (even if it's the same callback) triggers an immediate call with our node information, so the new coordinator will have it.
Adds some debug endpoints for looking into the DERP server.
The `api/v2/debug/derp/traffic` endpoint requires the `ss` utility to be present in order to function. I have *not* added the `iproute2` package to our base image as it adds 11MB, so this endpoint won't be useful by default. However, in a debugging situation, we could exec into the container and then `apk add iproute2`, or build a special debug image.
The `api/v2/debug/expvar` handler contains DERP metrics as well as commandline and memstats.

If we find the DERP metrics useful we could consider how to include them in Prometheus scrapes based on the tailnet `varz` package. That's for a later PR if at all.
When we exceed the db-imposed limit of logs, we need to communicate that back to the agent. In v1 we did it with a 4xx-level HTTP status, but with dRPC, the errors are delivered as strings, which feels fragile to me for something we want to gracefully handle.
So, this PR adds the log limit exceeded as a field on the response message, and fixes the API handler to set it as appropriate instead of an error.
Fixes#12030
This is a good example of the kind of thing I'd like to address with a time-testing lib. The problem is that there is a race between the watchdog starting it's timer and the test incrementing the time. What would make this easier is if the time-testing library could wait for and assert the call to start the timer before incrementing the time.
adds a watchdog to our pubsub and runs it for Coder server.
If the watchdog times out, it triggers a graceful exit in `coder server` to give any provisioner jobs a chance to shut down.
c.f. #11950
Annoyingly, prometheus Registry collects metrics async, which is causing our test to be racy. They also don't export enough from the Metric interface for us to replicate a synchronous collect, so we have to use Eventually to test.
Adds prometheus metrics to PGPubsub for monitoring its health and performance in production.
Related to #11950 --- additional diagnostics to help figure out what's happening
Moves monitoring of the agent v2 API connection to the yamux layer.
Present behavior monitors this at the websocket layer, and closes the websocket on completion. This can cause yamux to hit unexpected errors since the connection is closed underneath it.
This might be the cause of yamux errors that some customers are seeing
In any case, it's more graceful to close yamux first and let yamux close the underlying websocket. That should limit yamux error logging to truly unexpected/error cases.
The only downside is that the yamux `Close()` doesn't accept a reason, so if the agent becomes outdated and we close the API connection, the agent just sees the connection close without a reason. I'm not sure we log this at the agent anyway, but it would be nice. I think more accurate logging on Coderd are more important.
I've also added some logging when the monitor disconnects for reasons other than the context being canceled (e.g. agent outdated, failed pings).
* fix: strip timezone information from a date in dau response
Timezone information is lost, so do not forward it to the client.
* fix: timezone offset should be flipped
* Make tests deterministic
This PR solves #10478 by auto-filling previously used template values in create and update workspace flows.
I decided against explicit user values in settings for these reasons:
* Autofill is far easier to implement
* Users benefit from autofill _by default_ — we don't need to teach them new concepts
* If we decide that autofill creates more harm than good, we can remove it without breaking compatibility
